The research is focused on neural correlates of higher mental functions in man using neuropsychological, neurophysiological and behavioral approaches. The topics involve issues ranging from basic mechanisms of attention and emotion through functional architecture of memory to self-consciousness. The main goal of studies performed on healthy human subjects, patients with brain injuries, patients with neurodegenerative (Parkinson’s and Alzheimer’s diseases) and neurodevelopmental disorders (dyslexia, ADHD) is to get a better insight into the mind-brain relationship and to provide knowledge contributing to elaboration of better tools for clinical diagnosis and remediation.

• neuroimaging and electrophysiological methods are used enabling monitoring brain functions with high spatial and temporal resolution (functional Magnetic Resonance Imaging/Voxel Based Morphometry and Event-Related Potentials/Electromiography, respectively). These meth- ods are coupled with studies of the effects of focal brain lesions upon cognitive and/or emotional performance
• recent studies focus more on “functional integration” (connectivity) rather than functional localization using diffusion tensor imaging (DTI) and structural equation modeling (SEM).
Current research activities
